In the United States, Firefox uses OHTTP, which combines encryption and a proxy server, to conceal IP address and other identifying information before sending real-time search queries to Mozilla, preventing Mozilla from linking specific queries to the user.
Why it helps: This technology enhances user privacy by making it difficult for Mozilla to connect search queries to individual users, protecting search activity from being easily identifiable.
We use a privacy preserving technology called OHTTP , which combines encryption and a proxy server to conceal your IP address and other identifying information. Your real-time search query, along with technical, interaction, and IP-derived location data are passed through this OHTTP proxy by default before being sent to Mozilla. This helps prevent anyone (including Mozilla) from associating your specific query with you, or from combining it with unrelated information about your browsing activity.

For some Firefox users , Firefox routes DNS requests to a resolver service that has agreed to Mozilla’s strict privacy standards for resolvers . This provides added protection from privacy leaks to local networks and also from certain DNS security attacks.
System logs of DNS requests are deleted from the resolver service within 24 hours and are only used for DNS resolution.
Why it helps: This commitment to rapid data deletion minimizes the retention of potentially sensitive DNS request information, enhancing user privacy.
